- GLASS-FURNACE.

, Be it known that I, CHRISTIA N J. KOENIG,

a citizen of the United States, residing at Al ton,- county of Madison, and State of lllinois,-. have invented certain new and useful IriL- provemen-ts in Glass Furnaces,- of which the I, -My inventionrelatesx to i a glass-furnace which isparticularly adapted for feeding; or) delivering molten'glass'f to a number of auto- Ina-tic glass blowingmachines and the princi-pal object 'of'm'y invention is to construct a glass furnace havinga movable trough which receives the molten gla'ss-fromfthe meltingcated adjacent the outer wall of the furnace. A further obj ectof my invention is to com-- bine a 'trouglLWith a glass-furnace which trough is, heated, so as 'tomaintain the glass in a proper working condition, and there bein means rovi'ded'forim artin a reci roeating rotary motion to said trough.- 2

This'application should be read in connection with the application filed by me June 20,

1906, Serial No. 322,495.

My resent inventionconsists ofcertain I novel eatures of construction and arrange- 1nent ofparts which will be hereinafter more fully described, claimed, and shown in the drawings, in which- I Figure 'l isa horizontal section taken through my improved furnace immediately above the movable trough therein. .Fig. 2 is a vertical'section taken on a line 2 f Fig.1

Fig.3 is a vertical section taken on a line 3 3 of Fig. 1. Fig. 4 is a vertical section taken on a line. 4 4 of Fig. 1.'- f D Y Referringbynumerals to theaccom an- 'ng drawings, 1 designates acircular wall surrounds the chamber in which'the glass'is melted, saidchamber being divided by a",

transversely-arranged wall-2 into a meltingtank 3 and a'clearing or'working out tank 4. Formed in thecircular wall 1 at suitable distances apart are the verticall -arranged pairs of air and as inlet duct s 5, -t e upper ends ofn which disc arge intothe furnace immediately above the arch or top 6 thereof. Surrounding the wall 1 is a circular. wall 7 th'erebeing an annular air-space 8 formed between the walls 1 and 7, and surrounding said .wall 7 and arranged a, suitable distance away is a circular wall 9, and thus a circular compartment .10 is formed between the. Walls 7 and 9 Patented April 16,-1907.

which compartment is occupied by the mov able trough.

Formed through -the walls 1,' 7, and 9 to},

the rear of the chamber 8 1s anopening 11, through which the charge or material to be melted is delivered to the furnace, and formed through the Wall's'1-and 7 directly opposite this openin 11 is an opening 12, which leads fromthe c caring-chamber and is forthe 6 5 purpose of delivering the molten glass to the duct or canal. Formed through the wall9 directly ppposite the'opening 1.2 is an opening 13, which is for the purpose of giving access to the opening 12 to control the discharge of molten glass chamber of the furnace and dellversfsaid'j glass to the blowing-machines, which areilotherethrough.

'fFormed in the walls 7 and 9 at suitable distances apart are the vertically-disposed pairs o'f'gas-and air inlet ducts 14, the upper ends of which discharge into the upper portion of the compartment 10. Intersecting the outer wall 9 are. inwardly extending recesses or niches 15, which are to be occupied by theauto'matic glass-blowing machines, and'auxiliar walls 16 are formed immediately back of t ese recesses anclextend from the outer wall 9 to the wall 7.

Arranged for reciprocating rotary motion in the circular chamber 10 is a trough or re-v 5 ceptacle 1-7 in the form of 'a circular arc and which is constructed of an outer metallic shell 18, lined with fire-brick or fire-clay tile 19, the top of which'trough is open, arid fixed on the under side tligreof is a series of grooved 9 wheels 20, which travel upon a suitably-an ranged track2l, located on the bottom of the compartment 10.

r A circular rack 22 is fixed on the under sideof this trough, and meshing therewith is .a' pinion 23, carried by a shaft 24, which is "dIIVGIl in any suitable manner.

fjThe contentsof the chamber 3 in the furnacgand in the clearing-compartment 4 are maintained at the propertenlperatureby the 0 heat from the ignited gases which are deli'v cred through the ducts 5-, and the molten glass from the clearing-chamber 4 is allowed to discharge through the opening 12 into the trough 17. The molten glass while in said 5- trough isljmaintainedat the proper temperature by the heat of the burning gases which are delivered through the ducts 14. While the furnace is in use the shaft 24 is rotated for acertain number of revolutions in one di- I I0 rection, and thenthe' rotary motion is re versed and the pinion 3B, moshing with the and means whereby reciprocating rotarylmo' tion-is impartedto said trough. v 3. The combination with a, glass-furnace; of" ail-annular chamber formed around the? furnace, and atrough of circular-arc form ar rack consequently imparts a c0rrespond-' in'greciprocating trough 1.

rotary motion to the The lass-blowiw machines located in the recesses 15 are fed by'the automatic lassgathering mechanism, which dips into the eX- 1 posed open. top of the trougli and'as said trough is constantly in motion the glass after the glass is primarily heated and then delivered to the trohgh, and while in said trough the glass is-maintaine'd at the proper temperature byth'e direct application of heat in the trough-chamber. .t
